日凌,是一种天文现象。每年春分和秋分节气前后光顾地球,两次日凌时间达90天,对卫星产生严重干扰,有时卫星通信完全中断。在此期间,卫星用户接收信号时常受到干扰,投诉和技术咨询大量增加。卫星通信技术人员全面掌握日凌发生、形成以及何时到来的规律,向用户提前预报,并提供全面详细的技术咨询服务,减小日凌带来的负面影响,完善发稿流程,显得尤为重要。
Ling, is an astronomical phenomenon. Before and after the annual equinoxes and autumnal equinoxes patronize the earth, the two dates reach 90 days, causing serious interference to the satellites and sometimes satellite communications are completely interrupted. During this period, satellite users often receive interference signals, complaints and technical advice have increased substantially. It is especially important for satellite communications technicians to have a thorough grasp of the laws that have taken place, when they are formed, and when they arrive. They should give advance forecasts to users and provide comprehensive and detailed technical advisory services to reduce the negative impact brought by ZLTL.
